Status led lights solid red


brugola

Recommended Posts

I have a unistream UIS-WCB2 module.

With it I read a TC and run a heating system in PID.

During commissioning the status led turn solid red and all the analog IN/OUT stop working, the sinking OUTs also stop working.

All the other digital IN/OUTs still working properly.

Find no information about the meaning of a solid red status led in the documentation.

Any help will be apreciate

Hi Brugola,   this does appear to be a case of missing info.  Others may already know the answer.  

@Cara Bereck Levy  could you perhaps please follow up on this.

Status LED  A triple color LED. Indications are as follows:
Color             LED State       Status
Green             On                     Operating normally
                           Slow blink     Boot  
                           Rapid blink  OS initialization
Green/Red  Slow blink    Configuration mismatch
Red          Slow blink     No IO exchange
                   Rapid blink    Communication error  

Orange        Rapid blink     OS Upgrade

This info copy paste is lifted from the UIS-WCB2-SPEC-1-16 pdf. 

cheers, Aus

Hi Brugola, my post is telling the makers of the PLC that there IS missing information.  I am confirming your post.   That is why I have highlighted in blue, "Slow blink" and "Rapid blink"....there is no "On".

Cara is the head of the information section, and faces many difficulties in keeping literature up to date.

cheers, Aus

Hi people--two issues here.
First:

I will add the "The RED solid LED< status to the Help--If @Rivka says it, it is definitely so, she is a true guru 🙂

Second:
@Flex727, the info is in the Help, but I need to add a hyperlink so it is easy to find 🙂

 

@brugola, apologies. I do the Help and will immediately add this information to the next release, and I will notify the  Hardware people that they need to add it to the spec.
